“…For example, ner root systems enhance the complexity of nematode communities by increasing the relative abundance of high-trophic-level omnivores and predators (Zhang et al 2022). Tree species identity can affect soil fertility by regulating soil nematode communities in coniferous and broad-leaved forests (Liu et al 2023). Moreover, the nematode community structures differed signi cantly between soil origins obtained from either coniferous or broad-leaved forests (Fig.…”

“…Coniferous and broad-leaved trees exhibit signi cantly different effects on nematode trophic groups; for example, the abundance of predatory-omnivorous nematodes is greater in coniferous forest soils (Liu et al 2023). However, the presence of Abies alba reduced the metabolic activity of nematodes and negatively affected the abundance of bacterial and fungal feeding groups (Kondratow et al 2019).…”

“…Differences in litter quality among tree species have different effects on soil chemical properties (such as pH) and microbial communities (Sawada et al 2021;Tanikawa et al 2023), which, in turn, alter the trophic composition of nematodes (Cesarz et al 2013). Moreover, root-associated mycorrhizal types, either arbuscular or ectomycorrhizal, are related to nematode communities in forest soils (Kudrin et al 2021;Liu et al 2023). Mycorrhizal associations shape activity and biomass of soil bacterial and fungal communities which are food resources for nematodes, i.e., arbuscular mycorrhizal trees showed higher bacterial growth whereas ectomycorrhizal trees showed higher fungal growth (Heděnec et al 2020).…”

Purpose The effects of trees on soil nematode communities are related to nutrient cycles in forest ecosystems. We conducted greenhouse pot experiments to determine the effects of coniferous and broad-leaved tree species on soil nematodes. Methods Soils were collected from a coniferous plantation and broad-leaved forests. Seedlings of a coniferous tree (Cryptomeria japonica) and a broadleaved tree (Quercus serrata) were planted in soils derived from each species. After 11 months, seedling biomass, soil properties, and ectomycorrhizal fungal colonization of Q. serrata were measured. Soil nematodes were morphologically identified to the genus/family level and differentiated by community and trophic composition. Results C. japonica root biomass was significantly higher than that of Q. serrata regardless of the soil and nematode community structures were significantly different between the species. The fungal: bacterial ratio and density of fungivorous nematodes were significantly higher in broad-leaved soils. Herbivorous nematodes increased significantly in C. japonica seedlings grown in broad-leaved soils. Structural equation modeling indicated that soil origin and tree species directly regulated nematode trophic compositions. Conclusion Our findings suggest that tree species modify soil micro-food webs by affecting microbial abundance and nematode trophic composition. Specifically, C. japonica, with a larger root biomass, increased the number of herbivorous nematodes, whereas Q. serrata, with ectomycorrhizal fungal symbiosis, increased the number of fungivorous nematodes. Thus, tree species are tightly involved in shaping nematode communities in forest ecosystems through root traits and mycorrhizal types.

“…Microbivorous nematodes can modulate the structure and metabolic activity of microbial communities through selective predation [221,222]. Proper predation by nematodes can result in the rapid growth of microbiota, thereby enhancing its metabolic activity [223]. Simultaneously, the metabolites of nematodes serve as an additional energy source for the microbiota.…”

Plant–soil feedback (PSF) was initially developed in the field of agricultural practices. In recent years, PSF has been extended to various ecosystems. Root exudates, essential for the exchange of materials, energy, and information at the plant–soil interface, significantly influence PSF. However, how PSF is driven by root secretions and the role of these secretions in different PSF pathways still needs to be further explored, particularly in forest ecosystems. Soil nutrients, microbial communities, and nematodes are important research topics in the process of PSF driven by root exudates. Investigating these aspects driven by root exudates provides valuable insights into the complex interactions both above ground and below the surface. This research can offer theoretical support and guidance for building stable, healthy, and sustainable forest ecosystems in the future.

“…Beyond determining the strength, direction, and subsequent impacts of plant-soil feedback on the plant community, it is also essential to tease apart specific mechanistic 'black boxes' associated with plant-soil feedback to explain patterns as well as enhance predictions of plant-soil feedback. Liu et al (2022) conducted a greenhouse experiment showing how two broadleaf and two coniferous tree species from contrasting successional stages of a historically-logged subalpine forest on the eastern Tibetan Plateau influence the abundance and community composition of soil nematodes -a key group of soil biota previously identified in many studies to be a major biotic component driving plant-soil feedback. Specifically, Liu et al ( 2022) described a mechanism showing how tree species identity was important in altering soil abiotic properties differently via their influence on the abundances of various nematode trophic groups (i.e., biotic conditioning) during early succession.…”

Plants can strongly influence the performance of subsequent conspecific and heterospecific plants either positively or negatively by conditioning soil abiotic and/or biotic properties via plant litter and root activity. This process is commonly known as 'plant-soil feedback', which has been increasingly demonstrated to play a major role in plant community dynamics, ecosystem succession, and the maintenance of biodiversity (e.g.,
